Research and Analysis of an Intelligent Substation Risk Assessment Model
In view of the characteristics of the current intelligent substation with information physical system and the lack of in-formation system risk analysis in the traditional substation risk assessment,a substation risk assessment model under CPS is proposed.By analyzing the possible fault factors of substation,the substation risk transfer probability model based on CPS is analyzed.The substation risk assessment model is established according to the probability transfer model,and the assessment model is solved based on the improved satin bowerbird optimizer(SBO)algorithm,so as to quantify the substation risk index.In the experimental part,taking a typical IEEE intelligent CPS substation as an example,the simulation results verify the effec-tiveness and practicability of the proposed model.
